not sure that xrp always means the older stryle plug in battery, this drill is marked xrp and comes boxed with slide on batteries

I had heard XR referred to (youtube probably) as eXtra Runtime, referring to the better performance of brushless tools, I assume the XRP adds in 'pro' or 'performance'
that said I'm sure I've seen tools marked XR that aren't brushless at all
Dewalt often reuse the same housings for both XR (slideon) and XRP (plugin) tools, both ranges have both brushed and non brush versions around (often using the same gearbox etc- its the motor on the end of that gearbox that is different)
Dewalt have made it very confusing- as they have marked the 18v and 20v (XR in particular can be found with both 18v and 20v markings on the battery) and the XRP is even more confusing- with Nicad, NiMH and li-ion all were available in the XRP format- can be interchangably used in the XRP tool range, but require different chargers to be recharged...
A picture from your link...
Note that it is incorrectly using the XRP labeling on the tool (obviously havent bothered to have the casting modified for the metal gearbox housing), the plastic housing is using the new XR plastic parts (had to be modified to accept the XR slideon battery of course) and the battery itself is marked as an XR (18v this time, but they are also marked as 20v in some cases- despite both having the identical number of cells internally for both the 18v XR and the 20v XR (and the 18v XRP...)
You 'used' to be able to tell the differences in the XRP range (Nicad/NiMh or Li-ion) by the shape the Nicad and NiiMH used the 'rounder case' (but the lithiums had different tops, which would interchange in the tool, but not in the chargers) and the Li-ion had a squarer case- but these days that is no guarantee with clones flooding the market, often using li-ion in the 'round' case and the wrong 'tops'
Nicad 18v XRP (note the 'flat side' at the top- Nicad and NiMH both had this)
18v Li-ion XRP- (note the 'squarer' case (still fitted the same tools) and the two ridges on the top instead of the flat surface- this prevented them being used in a Nicad or NiMH charger...)
18v XR Li-ion (they have dropped the obsolete Nicad and NiMH chemistries by the introduction of the XR slideon range- I'm surprised they even still sell the Nicad or NiMH batteries in the XRP range, but they do...)
A '20v' XR- (same actual capacity and voltage (number of cells internally)- its a 'marketing ploy' to make them appear 'more powerful' than their 18v competitors lol- but its just using the nominal charging voltage rather than the nominal running voltage- identical capacity and number of cells internally lol)
Of course you can also use the XRP with XR batteries (some tools have this capability built into them, in the case of my shop-vac, it will accept either, or you can use XR batteries in a XRP tool with an adapter
'Multiport' (my shop vac)
LOL- my vacuum cleaner needs a good vacuuming!!! The XR slides onto the four visible metal 'tongues', the XRP goes into the 'roundish' hole...
I have an adapter lying around somewhere for the use of the XR battery in the XRP tools- I mostly use it as a 'huge' 5v USB powerbank for charging the phone on long trips, camping, fishing etc lol)- one hint for those who buy these- dont leave the battery in place when not using it- the USB charge circuit runs whenever the battery is plugged in and will flatten the battery in a week or two, even with nothing plugged into the USB charge port!!!
I run Dewalt because I started off with them (over twenty years ago)- and now have several chargers, (started off with the Nicads, but now using almost exclusively li-ion XRP on all toools except the chainsaw (XR, not available in XRP) and a sabre saw (ordered the wrong one and got the XR instead of the XRP)- I know several tradies that were more than slightly annoyed with the XR introduction, as they preferred to have a 'single battery and charger' across their entire tool range (as do I) but in reality- there is very little difference between any of the 'trade quality' tools (DeWalt has been slipping more and more into the 'home handyman' class, their quality is nothing like it used to be)
